As published on each lender's own page on 10 October 2026. Rates are personalised on your credit history, so the bottom of each range goes to applicants with excellent credit. *Each lender bases its comparison rate on $30,000 over five years. WARNING: This comparison rate is true only for the examples given and may not include all fees and charges. Different terms, fees or other loan amounts might result in a different comparison rate.
Lower floors outside the big banks, the fees behind each comparison rate and early payout fees are on the personal loan interest rates page.
- Debt consolidation: paired with closing or freezing the consolidated cards.
- Renovation under $50,000 where you do not have property equity to redraw against.
- Vehicle purchase where the car is too old for a secured car loan.
- Medical, wedding or holiday spending you cannot save for in time, borrowed over the shortest term you can manage.
A worked example: $25,000 over 5 years
At 7.25% p.a., the bottom of CommBank's fixed range: about $498 a month or $115 a week, $4,879 in interest.
At 16.99% p.a., Westpac's published median: about $621 a month or $143 a week, $12,271 in interest.
At 22.25% p.a., the top of CommBank's fixed range: about $694 a month or $160 a week, $16,642 in interest.
Where you land in a lender's range is worth about $11,760 of interest on this loan, far more than the repayment frequency. Fees come on top: CommBank's own total on $30,000 over five years at its 16.25% representative rate is $45,162 including fees.
WARNING: This comparison rate is true only for the examples given and may not include all fees and charges. Different terms, fees or other loan amounts might result in a different comparison rate. Comparison rates are calculated on a secured loan of $150,000 over 25 years for home loans and a loan of $30,000 over 5 years for car and personal loans, unless the lender states another basis. Business loans and equipment finance for a business purpose have no mandatory comparison rate.
